Abstract: A gas lens collet body for use in a gas tungsten arc welding torch includes a stem portion and an outer body shell constructed from a single piece of copper to provide increased electrical conductivity and a lower co-efficient of thermal expansion. An axially extending bore in the stem portion is adapted to receive a collet and electrode and an annular passage is formed between said stem portion and said outer body shell. A plurality of concentric fine mesh stainless steel screens are mounted in an outlet end of the annular passage and a plurality of holes interconnect the bore with the annular passage at an angle of 10.degree.-15.degree. relative to a longitudinal axis of the bore. Thus a shield gas introduced into the bore will pass through the angled passages into direct engagement with the plurality of screens to provide a stable, virtually turbulence free, shielding gas stream pattern.
